linux服务器密钥分发

Posted 2020-11-11

1.密钥分发脚本（一般是管理机进行分发，批量管理服务器）

#管理机创建公钥
ssh-keygen -t dsa -P ‘‘ -f ~/.ssh/id_dsa >/dev/null 2>&1

#服务器密码统一，可以这样玩
password=123456

#分发密钥
for i in "192.168.10.10" "192.168.10.11" "192.168.10.12" 
    do
        sshpass -p $password ssh -o StrictHostKeyChecking=no $i "mkdir -m 700 -p ~/.ssh/"
        sshpass -p $password scp -o StrictHostKeyChecking=no ~/.ssh/id_dsa.pub [email protected]$i:~/.ssh/authorized_keys
        sshpass -p $password ssh -o StrictHostKeyChecking=no $i "chmod 600 ~/.ssh/authorized_keys"
    done
